The following outline is provided as an overview of and topical guide to zoology:

Zoology – study of animals. Zoology, or "animal biology", is the branch of biology that relates to the animal kingdom, including the identification, structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek word ζῷον (zōon), i.e. "animal" and λόγος, (logos), i.e. "knowledge, study".^[1] To study the variety of animals that exist (or have existed), see list of animals by common name and lists of animals.

  • Nephrology - study of the urinary system
  • Neurology - study of the neural system
  • Pulmonology - study of the respiratory system
• Zooarchaeology - study of animal remains in relation to ancient people
• Zoogeography - Zoogeography is the scientific study of geographical distribution of animal species (both historic and contemporary) in the world
• Zoography - Zoography is study of animals and their habitats (also known as descriptive zoology)
